7 Claims.

This invention relates to a connection for fastening roofing or siding material on a roof or wall and my object is to devise simple means of this characterwhich will not only provide a water tight connection but one which will enable a defective portion of the roofing to be readily replaced without damage to the other portions of the roofing.

I attain my objects by securing a plurality of projections to the roof or wall structure. With these projections, are interlocked sockets formed in or carried by the sections of roofing or siding material so that no nails or prongs pass through the said material. The projections and sockets are so arranged. that the weight of the material tends to maintain the sockets in engagement with the projections. By pushing a defective section upwardly its sockets may be readily disengaged from their projections so that such defective section may be readily replaced by a fresh section.

The constructions are hereinafter more fully described and are illustrated in the accompanying drawing in which:

In the drawing like numerals of reference indicate corresponding parts in the difierent figures. i is a section of roofing or siding material which may be flat or corrugated as shown. Heretofore the common practice for securing these sections to roofs or walls has been to nail them on. Briefly, I nail or otherwise secure a plurality of projections 2 to the roof or wall base 3 and provide the sections l with sockets 4 adapted to fit over and interlock with the projections to support the sections on the roof or wall without passing any nails through the sections. The sockets are necessarily shorter than the length of the sections 5 to provide overlap.

The projections 2 may be triangular in plan and each has two upwardly and inwardly converging sides 5, 6 terminating in the apex of the projection. The said sides are undercut, if the projection is made of solid material such as the head of a nail, and the same effect is obtained by flaring the sides outwardly away from one another if the projection is made of sheet metal.

The sockets l extend lengthwise of the sections and are shaped to correspond to that of the projections 2 but are necessarily longer and are provided with converging sides i, 8 which are also undercut on their inner faces to interlock with the sides 5 and 6 of the projections when the sockets are slid downwardly over the projec tions. The sockets will be stamped in the roofing or siding material I when it is made of sheet metal and will be cast in the said material when it is made of tile or other refractory material.

The method of engaging a socket with a projection is to position a section over an underlying section with the wider part of its socket above the projection. A movement of the overlying section normal to the surfaces of the sections positions the projection in the socket and a second movement lengthwise of the upper section engages the sides of the projection with the sides of the socket.

Referring to Figs. 1 to 6, the projections 2 are 4 made of sheet metal stampings secured by nails 9 to the roof or wall base 3. The roofing or siding material I is also formed of sheet metal having the sockets 4 stamped therein. In this case, the projections will be nailed to the roof or wall so that they will register with the sockets.

In Figs. 7 and 8, the projections 2 are stamped in a strip of meta1 E0, the projections being spaced on the strip to match the vertical spacing of the sockets 4 in the material 1. The strips of metal H! are provided with nail holes for securing them to the base 3. Of course the strips will have to be spaced apart a distance equal to the distance between adjacent vertical rows of sockets. It will be understood that the strips may be arranged to run lengthwise of the base 3 instead of vertically thereof in which case the strips would be spaced apart a distance equal to that between adjacent horizontal rows of sockets.

In Figs. 9 to 11, I show the sockets i used with asphalt or composition shingles l These sockets 55 are formed of sheet metal stampings having converging sides l 8 which flare outwardly from one another relative to the lower edges of the sides to interlock with the projections 2. The undersides of the shingles I are recessed to receive the sockets 4*. The latter are provided with prongs 4 stamped from the upper sides 4 of the sockets and adapted to pass through the shingles and be bent over their upper surfaces l to secure the sockets in the recesses. The said upper surfaces are covered by a coating ll of fine gravel mixed in a suitable bonding material such as pitch so that it will adhere to the shingle and cover the openings formed by the prongs 4 to prevent any moisture from passing through the shingles.

In Fig. 12 is shown a modified form of the invention in which the projections 2 have converging sides 5 6 which are flared outwardly from one another and are spaced apart the width of a shingle I The latter has a socket 4 at its upper end which may be formed by bending in the upper edges of the shingle to form the converging sides 1 8* to interlock with the sides 5 6 Preferably the projections 2 are formed on strips Ill of metal which are secured to the base 3, the strips being spaced apart vertically of the base, one strip for each course of shingles. By staggering the projections 2 on successive strips i ii, the shingles i in successive courses will overlie the sockets A to shield them from the weather elements.

Instead of nailing the projections 2, 2 or the strips l0, Hi to the roof or wall, they may be secured thereto by means of prongs or clips I2 formed integral with the projections or strips. The clips are illustrated in Fig. 13 attached to an I beam and it is obvious that they may be shaped to fit any other steel structural member, such as an angle iron, in cases where the roofs or walls are not provided with a base 3.

From this description it is obvious that any defectivesection l or shingle l I may be readily removed by sliding it upwardly under the overlying sections or shingles to release its sockets from the projections interlocked therewith and then drawing it downwardly. A fresh section or shingle may be inserted by sliding it upwardly until its sockets are positioned for engaging the projections and then drawing it downwardly to interlock the sockets with the projections.

It will be understood that various modifications may be made without departing from the spirit of my invention.

What I claim as my invention is:

1. A connection for removably fastening roofing or siding material comprising-two parts having dovetailed sides, the said sides of each part converging upwardly towards one another so that the parts will form an interlocking connection by a limited sliding movement of one over the other, one of the said parts being adapted to be secured to a stationary member of a roof or wall and the other of said parts being on the roofing or siding material so that the latter may be readily secured to said stationary member by the aforesaid movement of the parts and be removed from said member by a reverse movement of the parts.

2. A connection for removably fastening roofing or siding material comprising a projection having upwardly converging sides which flare outwardly from one another; and a socket having correspondingly shaped sides to form an interlocking connection with the sides of the projection upon a limited sliding movement of the socket downwardly over the projection, the projection being adapted to be secured to a stationary member of a roof or wall and the socket being on the roofing or siding material, the interlocking connection being adapted to limit the sliding movement of the material relative to the projection and to prevent the material from being moved outwardly relative to the projection, and also to permit the material to be disengaged from the projection upon an upward sliding movement of the material relative thereto.

3. A roofing or siding formed in sections, each section having a triangular shaped socket, two adjacent sides of the socket being flared outwardly from one another relative to the underside of the section to engage and interlock with the sides of a projection corresponding in shape with the socket so that the socket will be held from movement outwardly relative to the projection, the socket being of lesslength than the section and being adapted to cover the projection when interlocked therewith, the socket also being releasable from the projection upon an upward sliding movement of the socket relative to the projection so that each section may be readily removed independently of the other sections.

4. Metallic roofing or siding formed in sections to cover a roof or wall, each section having a triangular shaped socket stamped therein, two adjacent sides of each socket being flared outwardly relative to the underside of the section; and strips of sheet metal secured to the roof or wall structure, each strip having a plurality of projections stamped therefrom adapted to be received in the sockets in the sections to engage the flared sides thereof so as to form interlocking connections therewith upon a downward sliding movement of the sections relative to the projections, the interlocking connections being adapted to limit the sliding movement and the outward movement of the sections relative to the projections, and to permit any section to be disengaged from its projection upon an upward sliding movement of the section relative thereto.

5. Securing means for sheet roofing comprising a plurality of projections having under-cut sides and adapted to be secured to a surface to be covered; and a plurality of sockets formed on or connected with the sheet roofing, the said sockets having under-cut sides and tapering longitudinally whereby a socket may be fitted over a projection and interlocked therewith by relative longitudinal movement to limit the outward movement of the roofing material relative to the projections.

6. Securing means according to claim 5 in which the projections are stamped from a strip of sheet metal.

7. Metallic roofing or siding comprising sections overlapping one another in echelon each section having a dovetailed recess formed in its underside spaced from each end of the section to thus provide for section overlap and having two opposite sides converging upwardly in the direction of the length of the section; and dovetailed projections adapted to be secured to the roof, each projection being of less length than the sockets and adapted to enter the wider part of the socket, whereby a socket may be engaged with a projection by a first movement normal to the surface of the sections and a second movement lengthwise of the sections.
